| Summary: | The impact of albedo on snow and sea ice mass balance has been studied. A one-dimensional thermodynamic snow/ice model incorporated with a number of albedo schemes was used to simulate the seasonal Baltic Sea ice. The instantaneous broadband albedo products from the AVHRR satellite instrument have been processed and compared with the modeled albedo. Under freezing weather conditions, the modeled surface albedo is generally in good agreement with the AVHRR product. A strong positive feedback of surface albedo creates rapid melting in early spring. The HIGHTSI model reproduces such events reasonably well by applying several advanced albedo schemes. A dramatic decrease of surface albedo is also revealed by the AVHRR data. The HIGHTSI model provides equally good results on snow and ice mass balance by using a re-constructed AVHRR albedo and calculated albedo from one of the most sophisticated albedo schemes. |
